Market overview

Heat pumps can be applied in

• Domestic buildings – in new buildings >10% market esp in

larger housing developments

• Commercial buildings – in large buildings > 40% market

• Greenhouses – closed greenhouse concept delivering heat

to surrounding users

• Industry – under survey with large potential in HT-

applications

Domestic houses

Scope of projects in Netherlands:

• Traditional market

• Newly built large housing areas

• Larger renovation projects with housing corporations

• Commercial buildings

• Collective flat buildings

• Mixed new and existing living quarters

Future markets

• Low energy buildings > nearly zero energy houses

EUROPEAN

COMMISSION




Applied heat pump concepts

Traditional heat pump technology:

• Collective heat pump with collective ground source

• Individual heat pumps with collective ground source

• Individual heat pumps with individual ground sourcecs

New heat pump technology:

• Individual air-water heat pump (mono)

• Individual air-water heat pump (hybrid system)

• Solar assisted heat pumps in low energy buildings

• Gas driven sorption and gas engine heat pumps
